The Sierra Club presented a subway map of the U.S. National Parks and is challenging eco-commuters to see how many stops they can hit. Though the map is “incredibly not to scale and also fictional,” it has inspired a flood of comments and shares on the group’s Facebook page. As one commenter wrote, “Only 9 for me, but this is my plan for retirement! Hope to get my card “punched” at most of these! And….hoping to ride horses through some of those!”
